Because shapes with parallel sides are weak. Triangular sides are more stable - which is why the steel infrastructure in buildings and bridges etc usually have triangular cross-members to add strength to the structure.

Which shape has more than one line of symmetry?
Many shapes have more than one line of symmetry. These include a rectangle, equilateral triangle, and a square. While a rectangle has two lines of symmetry, an equilateral triangle has three.
A rectangle and a triangle have equal areas?
it is possible, if the triangle is bigger than the rectangle, for example the rectangle has a base of 5 and height of 2-- so the area is 10; and then the triangle has a base of 5 and a height of 4-- the area is also 10.
Which polygon has fewer sides than a rectangle?
The triangle is the only one.
What shapes are stronger than triangles?
i dont think there is one but i want to be sure
Is a square stronger than a rectangle?
yes because they are more compact and balanced. The strongest shape is a triangle, so putting two obtuse triangles together to form a square is how most structures are created to be stable.
How is a triangle stronger than a rectangle?
the rectangle is sroger becuz its loger

Why is triangle stronger than a rectangle?
Given unchanging lengths of the sides, a triangle cannot change its shape. But given unchanging lengths of the sides of a rectangle, it can change its shape by some force by changing its angle measurements. If a 2d load were put on a rectangle, enough force could squish the rectangle into a parallelogram, whereas a triangle cannot change shape without changing the lengths of its sides or bending its sides out of shape (most likely into a curve).Given these properties, a rectangle can collapse its shape much more easily and is flimsy compared to a triangle.
What shapes have more than one line of symmerty?
Square, circle, rectangle, octagon, pentagon, triangle, hexagon, trapezoid, rhombus. These are just some
How is the rectangle different than the triangle?
A rectangle has 4 sides, while a triangle has 3 sides.
What shapes fit into a triangle?
anything smaller than the triangle
Is a polygon a rectangle or square?
A square is a type of rectangle. A rectangle is a type of polygon. Polygons are just 2D shapes with more than three straight sides, where there are no open ends or lines crossing over each other. Triangle and up, basically.
Is a trapezium stronger than a rectangle in building?
No.
Does a right triangle or a rectangle have the most right angles?
Rectangle has more right angles than the right triangle. The right triangle only has 1 right angle, while the rectangle has 4.
Why is a square stronger than a triangle?
It is NOT!

triangle
